본 고안은 액정주입장치에 관한 것으로서, 보다 상세하게는 액정의 주입을 신속하고 정확하게 주입시킬 수 있도록 주입구의 구조를 개선한 액정주입장치에 관한 것이다.The present invention relates to a liquid crystal injection device, and more particularly, to a liquid crystal injection device having an improved structure of an injection hole so that the liquid crystal can be injected quickly and accurately.
액정표시장치는 2장의 유리기판 사이의 대향면에 매트릭스상의 전극과 배향막을 적층 형성하여 평행 배치시킨 구조의 액정 셀 내부에 액정을 주입하여 전기 광학적 효과로 문자, 숫자, 기타 임의의 도안을 표시하는 장치이다.The liquid crystal display device injects liquid crystal into a liquid crystal cell having a structure in which a matrix electrode and an alignment layer are stacked and arranged on opposite surfaces between two glass substrates to display letters, numbers, and other arbitrary patterns with an electro-optic effect. Device.
이러한 액정표시소자를 제조함에 있어서, 2장이 포개어져 구성되는 액정셀의 내무로 액정을 주입할 때 모세관 현상을 이용한 주입방식과 진공을 이용한 흡입방식이 주로 적용되고 있다.In manufacturing such a liquid crystal display device, an injection method using a capillary phenomenon and a suction method using a vacuum are mainly applied when injecting a liquid crystal into the interior of a liquid crystal cell composed of two sheets.
제2도는 진5공을 이용하는 액정주입장치를 나타내는 도면으로서, 받침대(1)상에는 챔버(2)가 착탈 가능하게 설치되어 있으며, 이 챔버(2)내에는 액정 셀(3)을 지지하는 고정대(4)가 설치되어 있다.2 is a view showing a liquid crystal injection device using a vacuum hole, wherein a chamber 2 is detachably provided on a pedestal 1, and a fixing stand for supporting a liquid crystal cell 3 is provided in the chamber 2. 4) is installed.
그리고, 고정대(4)의 아래측에는 승강수단(5)가 설치되어 액정통(6)을 승강시키도록 되어 있으며, 받침대(1)에는 챔버(2)내를 진공상태로 유지시키기 위한 배기관(7)이 설치되어 진공펌프(도시생략)와 연통 설치되는 구성으로 되어 있다.In addition, a lifting means 5 is provided on the lower side of the fixing stand 4 to elevate the liquid crystal cylinder 6, and the pedestal 1 has an exhaust pipe 7 for maintaining the inside of the chamber 2 in a vacuum state. This structure is provided so as to be in communication with the vacuum pump (not shown).
이와 같이 구성되는 액정주입장치의 액정 주입 방식은, 먼저 액정셀(3)의 일측에 형성되어 있는 주입구가 아래쪽으로 되도록 액정통(6)의 상방에 배치한 다음, 챔버(2)를 닫고 진공펌프를 가동시키면 액정 셀(3)의 내부가 진공상태로 된다.In the liquid crystal injection method of the liquid crystal injection device configured as described above, first, the liquid crystal cell 6 is disposed above the liquid crystal container 6 so that the injection hole formed at one side of the liquid crystal cell 3 is downward, and then the chamber 2 is closed and the vacuum pump is closed. By operating, the inside of the liquid crystal cell 3 is in a vacuum state.
이어서 승강수단(5)로 고정대(4)를 상승 작동시켜서 액정 셀(3)의 주입구가 액정통(6)에 담궈지게 한 다음, 챔버(2)내의 진공을 해제시키면, 외부 대기압이 액정통(6)의 액정면에 작용하여 진공화된 액정 셀(3)의 내부로 주입이 이루어지게 된다.Subsequently, the holder 4 is lifted up by the lifting means 5 so that the inlet of the liquid crystal cell 3 is immersed in the liquid crystal cylinder 6, and then the vacuum in the chamber 2 is released. The injection into the inside of the vacuumed liquid crystal cell 3 acting on the liquid crystal surface of 6).
상술한 액정주입방식은 액정 셀의 내부 진공도를 높이기에 한도가 있어서 고효율의 진공장치를 갖추어야 하는 문제가 있고, 또 액정 주입시에는 주입구가 액정으로 막혀 버려 자칫 액정 셀의 진공도가 낮은 상태에서 주입을 시도하면 액정 셀의 모서리부분에 기포가 형성되어 버리는 단점이 있다.The above-mentioned liquid crystal injection method has a problem of having a high efficiency vacuum device because it has a limit to increase the internal vacuum degree of the liquid crystal cell. Attempts have a disadvantage that bubbles are formed in the corners of the liquid crystal cell.
이러한 문제점은 액정 셀에 2개의 주입구를 형성하여 놓고, 한쪽은 액정의 주입통로로, 또 다른 한쪽은 내부공기가 빠져 나가는 통로로 되게 하는 방법에 의해 근본적으로 해결될 수 있다.This problem can be fundamentally solved by forming two injection holes in the liquid crystal cell, one of which is an injection passage for the liquid crystal and the other is a passage through which internal air escapes.
일본국 특허공개공보 소화56-57023호는 2개의 통로가 개설된 액정 셀에 액정을 주입하는 방법을 제시하고 있으며, 이 방법에 따르면 액정 셀의 진공화와 액정의 주입이 동시에 행해지기 때문에 주입시간을 단축할 수 있고, 또 모서리부분에 기포가 생기지 않도록 액정을 주입할 수 있는 이점이 있다.Japanese Patent Laid-Open No. 56-57023 discloses a method of injecting a liquid crystal into a liquid crystal cell in which two passages are opened. According to this method, the injection time is performed because the liquid crystal cell is evacuated and the liquid crystal is simultaneously injected. It is possible to shorten, and there is an advantage that the liquid crystal can be injected so that no bubbles are generated in the corner portion.
그러나 실제에 있어서 액정 셀의 주입구는 6㎛정도의 미세한 갭으로 열려져 있는 것이므로 대기중에서 도관등으로 진공장치 및 액정주입장치와 액정 셀 사이를 연통시킨다는 것은 사실상 불가능하게 된다.In practice, however, since the injection hole of the liquid crystal cell is opened with a fine gap of about 6 μm, it is virtually impossible to communicate between the vacuum device and the liquid crystal injection device and the liquid crystal cell with a conduit or the like in the air.
따라서 액정 셀에 2개의 주입구를 형성하여 주입하는 방법은 현실적으로 시도하기 어려운 점이 많다.Therefore, the method of forming and injecting two injection holes into the liquid crystal cell has many disadvantages in reality.
본 고안은 상기한 바와 같은 종래 기술의 문제점을 해소하고자 안출된 것으로서, 본 고안의 목적은 액정셀에 2개의 통로를 개설하여 액정을 주입하는 방법에 특히 적합하게 사용될 수 있는 새로운 구조의 액정주입장치를 제공하는데 있다.The present invention is conceived to solve the problems of the prior art as described above, the object of the present invention is to open a liquid crystal cell of the new structure that can be particularly suitable for the method of injecting the liquid crystal by opening two passages To provide.
상기한 바와 같은 목적을 달성하기 위하여, 본 고안은 통상의 진공팜프로 연통되는 배기관의 종단부에, 통상의 셀이 보유하는 주입구의 주변을 둘러 쌓아 외부와 격리시키는 진공팩이 설치됨과 아울러 상기한 배기관의 도중에 밸브를 개재시킨 구성으로 함으로써 액정 셀의 주입구로 도관을 삽통시키지 않고도 액정 셀의 내부 진공화 및 액정 주입을 가능케 한 액정주입장치를 제안한다.In order to achieve the above object, the present invention is the end of the exhaust pipe communicated with a conventional vacuum pamp, the vacuum pack is installed to surround the inlet surroundings of the normal cell to isolate from the outside as described above The liquid crystal injection device which enables the internal vacuum of a liquid crystal cell and liquid crystal injection is possible without making a conduit penetrate through the inlet of a liquid crystal cell by setting it through the valve in the middle of an exhaust pipe.
이하 본 고안의 바람직한 실시예를 첨부한 도면에 따라 더욱 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
제1도는 본 고안에 관련된 액정주입장치의 사용예를 나타내는 측단면도로서 부호(10)은 액정 셀을 지칭한다.1 is a side cross-sectional view showing an example of use of a liquid crystal injection device according to the present invention, and reference numeral 10 denotes a liquid crystal cell.
액정 셀(10)은 위 아래측 변에 주입구(11)(12)가 뚫려진 구조로 되어서 액정 주입시에는 하측의 주입구(11)가 액정통(16)에 담궈지게 된다.The liquid crystal cell 10 has a structure in which the injection holes 11 and 12 are drilled in the upper and lower sides thereof, so that the lower injection hole 11 is immersed in the liquid crystal container 16 when the liquid crystal is injected.
본 고안에 관련된 액정주입장치는, 액정 셀(10)의 상측 주입구(11) 주변을 감싸서 외부로부터 격리시키는 진공팩(13)을 배기관(14)의 종단부에 보유하고 있으며, 또한 이 배기관(14)의 도중에는 밸브(15)가 장착되어 있다.The liquid crystal injection device according to the present invention has a vacuum pack 13, which wraps around the upper injection port 11 of the liquid crystal cell 10 and isolates it from the outside, at the end of the exhaust pipe 14, and also has the exhaust pipe 14. The valve 15 is attached in the middle of the figure.
상기한 배기관(14)은 도시하지 않은 진공펌프로 연통되는 것이다.The exhaust pipe 14 communicates with a vacuum pump (not shown).
그리고 상기한 진공팩(13)은 액정 셀(10)의 주변을 기밀스럽게 감쌀 수 있는 재질, 예를 들면 연질 고무나 스폰지 등의 패킹재를 포함할 수도 있다.In addition, the vacuum pack 13 may include a material that can enclose the periphery of the liquid crystal cell 10, for example, a packing material such as a soft rubber or a sponge.
또, 액정 셀(10)의 규격별 차이에 대응하기 위하여 여러가지 크기의 진공팩(13)을 준비하여 놓고 이들 중에서 임의로 선택하여 배기관(14)에 착탈시켜 사용할 수도 있다.In addition, in order to cope with the differences according to the specifications of the liquid crystal cell 10, vacuum packs 13 of various sizes may be prepared, and may be arbitrarily selected from these to be attached to and removed from the exhaust pipe 14.
이와 같이 구성된 본 고안의 액정주입장치는 제1도에 도시한 바와 같이 액정 셀(10)의 주입구(12)를 아래쪽으로 하여 액정통(16)에 담그고, 주입구(11)측에 진공펌프와 연결된 진공팩(13)을 씌운 다음, 밸브(15)를 열러놓고 진공펌프를 가동시키게 되면 진공팩(13)과 액정 셀(10)의 내부가 진공상태로 되는 것과 동시에 액정통(16)에 수용된 액정이 액정 셀(10)내로 흡입된다.The liquid crystal injection device of the present invention configured as described above is immersed in the liquid crystal container 16 with the injection hole 12 of the liquid crystal cell 10 downward as shown in FIG. 1, and connected to the vacuum pump at the injection hole 11 side. When the vacuum pack 13 is covered and the valve 15 is opened and the vacuum pump is operated, the inside of the vacuum pack 13 and the liquid crystal cell 10 is in a vacuum state and the liquid crystal contained in the liquid crystal container 16. This is sucked into the liquid crystal cell 10.
이러한 액정주입상태를 목측하면서 액정 셀(10)내에 액정이 충만하게 되면, 밸브(15)를 잠궈서 액정의 주입이 중단되게 조치한다.When the liquid crystal is filled in the liquid crystal cell 10 while the liquid crystal injection state is observed, the valve 15 is locked to take an injection of the liquid crystal to be stopped.
이어서 하측 주입구(12)를 본딩처리하여 밀봉시킨 다음, 다시 액정셀(10)에 보다 낮은 진공부압을 가한다.Subsequently, the lower injection hole 12 is bonded and sealed, and then a lower vacuum negative pressure is applied to the liquid crystal cell 10 again.
이렇게 액정 셀(10)로 보다 낮은 압력의 진공부압을 가할 때는 하측 주입구(12)가 본딩처리되어 있기 때문에 주입된 액정은 빨리 나오지 않고, 그 내부에 존재할 수 있는 미세기포만이 진공부압에 이끌려 흡인 제거된다.When the lower pressure inlet 12 is applied to the liquid crystal cell 10 in this manner, the lower injection hole 12 is bonded, so that the injected liquid crystal does not come out quickly, and only the microbubbles that may exist therein are attracted to the vacuum negative pressure to remove suction. do.
다음에 진공팩(13)을 액정 셀(10)의 상측부에서 떼어 분리하고, 액정 셀(10)의 상측 주입구(11)로 본딩처리한다.Next, the vacuum pack 13 is removed from the upper portion of the liquid crystal cell 10 and separated, and bonded to the upper injection hole 11 of the liquid crystal cell 10.
이상과 같이 본 고안의 액정주입장치는 액정 셀의 주입구가 미세함에도 불구하고 진공팩을 이용하여 간단하게 액정을 주입할 수 있기 때문에 액정주입시간을 단축시킬 수 있고, 또한 액정 셀의 내부에 기포가 생기지 않게 주입할 수 있어서 불량률을 저하할 수 있다는 실용성을 가지고 있다.As described above, the liquid crystal injection device of the present invention can shorten the liquid crystal injection time because the liquid crystal can be easily injected by using a vacuum pack despite the fine injection port of the liquid crystal cell, and bubbles are formed inside the liquid crystal cell. It has the practicality of being able to inject | pour so that it may generate | occur | produce so that a defect rate may be reduced.
